Chemical Compositions of Steels

CS 70 and C67
Carbon steel which, after hardening and tempering, has excellent strength and fatigue resistance which makes them ideal for spring pins, both coiled and slotted.

AISI 304 and WS 1.4301
Austenitic stainless steel, unhardenable and with low magnetic permeability, used for both coiled and slotted spring pins where corrosion resistance is needed.

WS 1.3505
Hardenable high carbon steel with chrome content used for through-hardened dowels in the metric range.

WS 1.4305 and 303S31 (A2)
Unhardenable austenitic stainless steel with low magnetic permeability used for dowels, grooved pins, taper pins and threaded spacers where corrosion resistant properties are required.

WS 1.4571 and 316S11 (A4)
Unhardenable austenitic stainless steel with low magnetic permeability, but with very high corrosion resistance used for dowels.

431S29 (C1)
A hardenable martensitic stainless steel used for dowels requiring the maximum shear strength, combined with corrosion resistance

WS 1.0718 (9SMnPb28)
Leaded mild steel used for dowels, taper pins and grooved pins.

S300 Pb
Leaded mild steel used for threaded spacers.

AISI 1010
Low carbon steel used for roll-formed clearance spacers

WS 1.0503 (C45k)
Standard Key steel with a minimum tensile strength of 60 Kg/mm²

Silver Steel to BS 1407
A through-hardenable high carbon steel used for dowels and small turned parts
